Error after installation: django.db.migrations.exceptions.NodeNotFoundError

[saschafoerster]

I added pretalx-public-voting to my Dockerfile

FROM pretalx/standalone:latest
USER root
RUN pip3 install pretalx-public-voting
USER pretalxuser

I built a new container from that: docker build -t bonndigital/pretalx .

And with docker-compose I successfully started pretalx with the plugin installed:

version: '2'
services:
  pretalx:
    # image: pretalx/standalone:latest
    image: bonndigital/pretalx
    #build: .
    container_name: pretalx
    restart: unless-stopped
    ports:
      - "8346:80"
    volumes:
      - /etc/pretalx/pretalx.cfg:/etc/pretalx/pretalx.cfg:ro
      - /var/pretalx-data:/data
      - /var/run/mysqld:/var/run/mysqld
      - /var/run/redis:/var/run/redis
    labels:
       traefik.docker.network: "pretalxdocker"
       traefik.enable: "true"

When I try to migrate and prepare databases I get this error: docker exec -it pretalx pretalx migrate

pretalx-public-voting is currently under development and not ready for production use. It only works with the development version of pretalx and even then is in no shape to be used at this point.
